Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding device technology, and more specifically, to a polypropylene feeding device for uniform mixing. Background Technology
[0002] In the processing of polypropylene materials, the uniformity of mixing has a decisive impact on the performance of the final product. Traditional polypropylene feeding devices usually adopt a structure in which the stirring rod is connected to the housing through a bearing. The material is mixed by rotating and stirring. However, in actual long-term operation, the bearing between the stirring rod and the housing is in a relatively closed working environment and lacks an effective automatic lubricant replenishment mechanism. During continuous operation, the lubricant in the bearing is prone to gradually fail due to high temperature evaporation, wear and tear, or contaminant intrusion.
[0003] In the existing technology, the bearing lubrication of the polypropylene feeding device requires the operator to manually drip lubricant onto the bearing surface with the aid of tools. This maintenance method not only increases the intensity of manual labor, but also causes the bearing to rotate poorly due to untimely lubrication, which in turn causes the stirring rod to move unstably and ultimately affects the uniformity of material mixing. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a polypropylene feeding device for uniform mixing, so as to solve the problem that in the prior art, operators need to manually drip lubricant onto the bearing surface with the aid of tools. This maintenance method not only increases the intensity of manual labor, but also causes the bearing to rotate poorly due to untimely lubrication.
[0005] To solve the above technical problems, the present invention provides the following technical solution: a polypropylene feeding device for uniform mixing, comprising a feeding device body and a stirring rod, a fixed seat is installed on the right side of the feeding device body, a bearing is installed on the left side of the inner wall of the fixed seat, a storage tank is opened on the upper side of the interior of the fixed seat, and an oil outlet is opened on the rear side of the bottom wall of the storage tank.
[0006] The fixed base has a sliding groove on its rear side, a limiting plate is slidably connected to the front side of the inner wall of the sliding groove, a pull rod is installed on the rear side of the limiting plate, a spring is sleeved on the outer side of the pull rod, and a piston is installed on the front side of the limiting plate.
[0007] The piston's front end passes through the slide groove and is inserted into the lower side of the inner wall of the oil outlet. The pull rod passes through the rear side of the fixed seat. One end of the spring is installed between the limiting plate and the other end is installed between the inner wall of the slide groove.
[0008] The feeding device body has multiple threaded holes on its right side, and fixing bolts are inserted into the four corners of the fixing seat. Washers are fitted on the outside of the fixing bolts, and rubber ball clamps are installed on the upper and lower sides of the left side of the washers. Two slots are opened at the four corners of the fixing seat.
[0009] The left part of the fixing bolt passes through the fixing seat and is threadedly connected to the threaded hole.
[0010] The rubber ball is engaged with the inner wall of the groove, and the rubber ball is in a state of compression deformation.
[0011] The right end of the stirring rod passes through the fixed seat and is inserted into the middle of the bearing, and the bottom front end of the oil outlet hole is in contact with the rear side of the bearing.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In the above solution, by unblocking the oil outlet, the lubricant in the storage tank is continuously supplied to the rear contact surface of the bearing through the oil outlet. When the stirring rod is running, the lubricant forms a dynamic oil film under the action of centrifugal force, achieving uniform lubrication of the bearing around the entire circumference and improving the smoothness of the stirring rod's operation. This eliminates the need for workers to use auxiliary tools to replenish oil, thereby improving the mixing uniformity of the feeding device and the stability of equipment operation.

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0023] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a polypropylene feeding device for uniform mixing, including a feeding device body 1 and a stirring rod 3. A fixed seat 2 is installed on the right side of the feeding device body 1, and a bearing 12 is installed on the left side of the inner wall of the fixed seat 2. A storage groove 5 is opened on the upper side of the interior of the fixed seat 2, and an oil outlet 6 is opened on the rear side of the bottom wall of the storage groove 5. The right end of the stirring rod 3 passes through the fixed seat 2 and is inserted into the middle of the bearing 12, so that the stirring rod 3 and the feeding device body 1 are rotatably connected by the bearing 12, so as to mix the raw materials in the feeding device body 1. The bottom front end of the oil outlet 6 is in contact with the rear side of the bearing 12, so as to facilitate the guidance of lubricant to the rear side of the bearing 12 and increase its rotation smoothness.
[0024] First, pull the piston 11 backward and slide it away from the lower side of the inner wall of the oil outlet 6, thereby releasing the restriction on the oil outlet 6. At this time, the lubricant in the storage tank 5 will flow to the rear side of the bearing 12 through the oil outlet 6, so that when it rotates, the lubricant will be evenly coated on the surface of the bearing 12, thereby increasing the smoothness of the rotation of the stirring rod 3, and thus improving the mixing effect of the feeding device body 1.
[0025] Example 2: Based on Example 1, in order to facilitate oil replenishment of the bearing 12, a sliding groove 10 is provided on the rear side of the interior of the fixed seat 2. A limiting plate 7 is slidably connected to the front side of the inner wall of the sliding groove 10. A pull rod 9 is installed on the rear side of the limiting plate 7. A spring 8 is sleeved on the outer side of the pull rod 9. A piston 11 is installed on the front side of the limiting plate 7. The front end of the piston 11 passes through the sliding groove 10 and is inserted into the lower side of the inner wall of the oil outlet 6, thereby blocking the oil outlet 6 with the piston 11 so that it can be opened for subsequent oil replenishment. The pull rod 9 passes through the rear side of the fixed seat 2, thereby facilitating operation by the operator. One end of the spring 8 is installed between the limiting plate 7 and the other end is installed between the inner wall of the sliding groove 10, thereby using the elastic force of the spring 8 to push the piston 11 to always remain inserted with the lower side of the inner wall of the oil outlet 6.
[0026] First, pull the lever 9 backward, causing the limiting plate 7 to slide backward along the inner wall of the slide groove 10 and compress the spring 8, making it compress within the inner wall of the slide groove 10. During this process, the piston 11 will slide backward synchronously and disengage from the lower side of the inner wall of the oil outlet 6, thereby releasing the restriction on the oil outlet 6. At this time, the lubricant in the storage tank 5 will flow through the oil outlet 6 to the rear side of the bearing 12, allowing it to evenly coat the surface of the bearing 12 during rotation. Then, the lever 9 can be released, and the spring force of the spring 8 will push the limiting plate 7 forward to reset, causing the piston 11 to continue to insert into the lower side of the inner wall of the oil outlet 6 to continue blocking the oil outlet 6, facilitating subsequent oil replenishment. This increases the smoothness of the rotation of the stirring rod 3, thereby improving the mixing effect of the feeding device body 1.
[0027] Example 3: Based on Example 2, in order to facilitate the removal of the fixed seat 2, multiple threaded holes 4 are provided on the right side of the feeding device body 1. Fixed bolts 13 are inserted into the four corners of the fixed seat 2. Washers 16 are fitted on the outside of the fixed bolts 13. Rubber retaining balls 15 are installed on the upper and lower sides of the left side of the washers 16. Two retaining grooves 14 are provided at the four corners of the fixed seat 2. The left side of the fixed bolts 13 passes through the fixed seat 2 and is threadedly connected to the threaded holes 4, thereby fixing the fixed seat 2 to the feeding device body 1. The rubber retaining balls 15 are engaged in the inner wall of the retaining grooves 14 and are in a compressed deformation state, which facilitates the subsequent replacement of the washers 16. Moreover, the installation of the fixed seat 2 can be carried out without the aid of additional washers 16.
[0028] When it is necessary to disassemble the fixed seat 2, first unscrew the four corner fixing bolts 13 and disconnect them from the threaded holes 4. At this time, the bearing 12 can be replaced or the lubrication component can be maintained. After that, the fixed seat 2 is reset and the four corner fixing bolts 13 are installed. Since the four corners of the fixed seat 2 are equipped with shims 16, the installation operation can be carried out without the need for additional shims 16. At the same time, the shims 16 are fitted with the fixed seat 2 by the rubber ball 15 into the inner wall of the slot 14, which makes it convenient to replace the shims 16 individually when they are damaged, thereby reducing the replacement cost and improving the overall performance of the feeding device body 1.
[0029] The working process of this utility model is as follows:
[0030] In use, first pull the lever 9 backward, causing the limiting plate 7 to slide backward along the inner wall of the slide groove 10 and compress the spring 8, so that it is in a compressed state on the inner wall of the slide groove 10. During this process, the piston 11 will slide backward synchronously and disengage from the lower side of the inner wall of the oil outlet 6, thereby releasing the restriction on the oil outlet 6. At this time, the lubricant in the storage tank 5 will flow to the rear side of the bearing 12 through the oil outlet 6, so that when it rotates, the lubricant will be evenly coated on the surface of the bearing 12. Then, the lever 9 can be released, and the spring force of the spring 8 will push the limiting plate 7 forward to reset, and drive the piston 11 to continue to insert into the lower side of the inner wall of the oil outlet 6 to continue to block the oil outlet 6, so as to facilitate subsequent oil replenishment, thereby increasing the smoothness of the rotation of the stirring rod 3, and thus improving the mixing effect of the feeding device body 1.
[0031] When it is necessary to disassemble the fixed seat 2, first unscrew the four corner fixing bolts 13 and disconnect them from the threaded holes 4. At this time, the bearing 12 can be replaced or the lubrication component can be maintained. After that, the fixed seat 2 is reset and the four corner fixing bolts 13 are installed. Since the four corners of the fixed seat 2 are equipped with shims 16, the installation operation can be carried out without the need for additional shims 16. At the same time, the shims 16 are fitted with the fixed seat 2 by the rubber ball 15 into the inner wall of the slot 14, which makes it convenient to replace the shims 16 individually when they are damaged, thereby reducing the replacement cost and improving the overall performance of the feeding device body 1.
